What is the best way to avoid divide by zero with Explorer.Series.divide/2
I have two Explorer.Series and want to divide the first series with the second series containing 0.
series0 = Explorer.Series.from_list([1, 2, 3])
series1 = Explorer.Series.from_list([0, 1, 2])
Explorer.Series.divide(series0, series1)
Then it throws an error,
thread '<unnamed>' panicked at 'attempt to divide by zero', /rustc/dc80ca78b6ec2b6bba02560470347433bcd0bb3c/library/core/src/ops/arith.rs:507:1
** (ErlangError) Erlang error: :nif_panicked
(explorer 0.2.0) Explorer.PolarsBackend.Native.s_div(shape: (3,)
Series: '' [i64]
[
1
2
3
], shape: (3,)
Series: '' [i64]
[
0
1
2
])
(explorer 0.2.0) lib/explorer/polars_backend/shared.ex:17: Explorer.PolarsBackend.Shared.apply_series/3
I think NaN or Infinity is the right result for dividing by zero. But I don’t know how to get that result with Explorer.Series.divide/2.
